Columnist: While defense spending in our country is almost certainly subject to waste, proposing that we could solve our budget crisis even by entirely eliminating such waste is unjustified. Even dramatic cuts in defense spending will be insufficient to cover the expanding cost of health care.
Which of the following is NOT an assumption required by the columnist’s argument?The columnist’s logic is: if even very large defense cuts cannot cover the growing health care cost, then eliminating “waste” (which is at most a large cut) cannot solve the budget crisis. This relies on linking “solving the budget crisis” to covering health care costs, and on the idea that proposing a fix is unjustified if it would be insufficient. It does not require assuming there are no other ways to cover health care costs, because the target claim is that eliminating waste
by itself could solve the crisis.
(A) If we cannot cover the expanding cost of health care, then we cannot solve the budget crisis.
Required. Without this, “cannot cover health care costs” would not imply “cannot solve the budget crisis.”
(B) If a proposed measure is insufficient to solve a crisis, then proposing it is unjustified.
Required. This is the rule that connects “insufficient” to
unjustified.
(C) Eliminating waste in defense spending would constitute a dramatic cut in defense spending.
Required. The columnist moves from “even dramatic cuts are insufficient” to “eliminating waste is insufficient,” so they need eliminating waste to fall within that category (or be smaller).
(D) There are no other means to cover the expanding cost of health care.
Not required. Even if there are other means, the columnist can still say eliminating defense waste alone will not solve the crisis, because the defense cut still would not cover the health care cost that is driving the problem. So this extra claim is not needed.
(E) The columnist’s calculations are correct and complete.
Not required as an assumption in the reasoning structure. The argument can proceed conditionally from its stated claim about insufficiency; this choice is about factual accuracy, not the logical link.
Answer: (D)
